[Objective] This study aimed to investigate the genetic relationship among waxberry (Myrica rubra Bieb.et Zucc) cultivars in Jiangsu Province. [Method] Eighteen waxberry cultivars (lines) in Jiangsu Province were analyzed using ISSR-PCR method, and molecular phylogenetic tree was constructed using UPGMA method. [Result] A total of 70 DNA fragments were amplified with nine screened primers, including 43 polymorphic fragments, accounting for 61.4% of the total number of amplified fragments; 18 waxberry cultivars (lines) were clustered into 6 categories with the genetic distance of 0.14, indicating that there is partial isolation on the basis of gene exchange between waxberry cultivars (lines) in Jiangsu Province. [Conclusion] This study provided scientific basis for the protection and utilization of waxberry germplasm resources and cultivation of new varieties.
